-' l Application .rune 5, 1931. serial. 1mi-542,413` f1 Claim.' (ci. :i5- 6i This invention relates to lawn rollers or the like, usable for any ypurposeA for which such dev vices may be employed, and has for its object the production of a roller comprising parts of spe- 5 cial construction and combination; whereby Yit i's v flbelieved a structure is formed of a particularly simplel nature, easily manufactured and assem pbled, and capable of withstandingrthe ,hardest service for the greatest length of time without at-v tention or repairs.

In the accompanying drawing are illustrated theV different parts and their construction and combination is set forth. Ofthe; drawing, Fig. vl

` is a vertical longitudinal section of the roller and i of the handle, the remainder of the handle frame being 'shown in full lines. `Fig.`2. is -a sectional view showing the electrically welded seam of the f drum or roller. Fig. 3 shows the'circularly electrically welded edge connection of the head of the roller and cylinder. Fig. 4 is a sectional view lshowing the circumferential welded connection of the re-enforcing center plate and the head.Y Throughout the drawing and descriptionthe same number is used to refer to the same part.

Considering the drawing, thehandlel is secured at the upper ends of the sides 2 and 3 of the handle frame. vThose sides are made of channeliron or like metal which is found to afford' the greatest strength with the least weight, and the channel iron sides cannot be readily bent orl distorted by any amount of rough usage. The channel iron sides are usually connected by ,a brace plate 4 as set forth. n

- The roller is comprised of a sheet of metal bent into cylindrical shape designated bynumber 5, and the end edges of the cylinder thus formed `are turned inwardly as edge 6 in Fig. l. The cylinder has two heads '7 '-inone of which is a removableY screw plug 8 in orderthat the cylindermay be lled with water for weight in the customary manner. An advantageous feature of the construction of the roller comprises the in-turned f circumferential edges,6,.best vshown inFig. 3. In actual manufacturing it has been found that the in-turned edges of the cylinder `with the heads 7 bearings, and the section includes also a portioni with ball bearingsV 1`2`to receive the'rjournals or .ends ofthe axis. ',Itwill be observed that the b all bearings'12 are double bearings, and particularly@ that the ball races are `spaced at relativelycon` j c siderable:distances apart on the end of ,the pro-".601

jecting axis This is intentional and veryad- `,vantageous inia ,roller using water as the weight.

The surging weight of water during theoperationv is especially severe onv bearings and quickly/dise, Y torts them. yWithajplurality of sets of bearings` 65 somewhat widely separated on the ends `of-the'l axis as illustrated, the displacement of the bearcorrespondingly extended. f

In Fig. 2 will .be noted the seam 13 :electrically 70 welded.. which connectsthemeetingsends 0f the sheet of metal ofl which thefroller is formed. Any desired .method vof welding or:cast welding may be employed. In Fig.'3 is shownthe circumf ferential electrically Weldedv junction of .the head a and cylinder,4 and in Fig. .4 the like welded edge portionor" the re-enfor'cing plate on thehead. Thus -welded the parts' are/found rto possess extraordinary strength jas a Whole, and thejconings is greatly reduced and the life ofthe roller struction is the most economical with which this Having now describedthisinvention, I'claimr-gd Y p Ina lawn roller, the combination of Va liollciw'V 854) cylindrical body portion adapted to be iilled with v water, a removable plug, circular heads in said` lcylindensaid plug being inserted in one ofsaid' heads, anaxispassing through the body, bearings carried by the endsof the axisa handle confnected with the said bearings, the 'saidcylindrical -portion of the roller having circumferential edges' turnedinwardly, and the said circular heads havgj ing welded joints'with said cylindrical portion,`
